RESUMEN
OBJECTIVE: To clarify the pathogens in plateau hospital-acquired pulmonary infection and their antimicrobial susceptibility so as to provide scientific basis for clinical first-line treatment in the rational use of antibacterial drugs. METHODS: The bacteriological culture and drug susceptibility experiment on sputum and bronchial douche fluid collected from 1 396 patients with hospital-acquired pulmonary infection in our hospital from 2004 to 2006 as well as the filed medical records were analyzed retrospectively. RESULTS: 789 positive bacteria were isolated, of which, 77.82% (614/789) were gram-negative bacilli (GNB), with Klebsiella spp showing the highest percentage, accounting for 53.91% (331/614); 21.04% (166/789) were gram-positive bacteria, with staph showing the highest percentage, accounting for 46.99% (78/789).Most of the GNB were sensitive to imipenem, sulbactam/cefoperazone, then to aminoglycosides. The susceptibility rate of Gram-positive bacteria to vancomycin was 90.36%. CONCLUSION: Gram-negative bacilli were the main hospital infection pathogens, which were sensitive to imipenem, sulbactam/cefoperazone but highly resistant to ceftazidime, which calls for attention in the clinic.
RESUMEN
@#中国盲文是我国视力残疾人使用的触觉凸点文字。规范、统一中国盲文标准，将有力地促进视残者文化事业的发展。本文对盲文的起源与发展进行了简要的介绍，论述了“中国盲文”国家标准主要内容与制定依据。并阐明贯彻“汉语双拼盲文方案”是广大视力残疾人与盲文工作者的紧迫作务。
